A while ago I had a problem with Ami's fins being torn up, I decided it was from the plants & had her out of the tank for probably a month. I also had to take Zetta out of the tank because she was missing scales on her stomach, not sure why, but they are growing back.
Thursday night I reintroduced Ami. All of my girls are peaceful except for Drina & sometimes Ami. Drina can tend to be a little nippy & sometimes Ami flares her fins. They are obviously the two top girls.
Drina was being a major you-know-what so I had to take her out; Ami, Delta & Vegas were all doing great!

Tonight I look in my tank & Delta's fins are shredded & she isn't swimming. They were a little torn earlier, along with Ami's but I hadn't seen any fighting or chasing. Delta is now in a hospital tank, Ami is floating in a cup, & nice little Vegas gets the whole tank to herself!

All of the plants (minus 2 small silk ones & 1 real one) are plastic. I didn't think that I'd have problems with them because they are all really soft & I don't see how a plant could do this kind of damage to Delta's fins. But I have a couple of the same plants in two of my males' tanks (neither of their fins have EVER been torn).

Okay! I'm on my way to Petco right now!
Are female betta's fins more delicate than the males? Because none of my males who have the same plants as the girls, have torn fins. Even when there is only 1 girl in the whole sorority for whatever reason, she manages to tear her fins..

Sororities are great, (and here is that word) but. Some females just don't seem to belong in a sorority. I have tried reintroducing 4 of mine many times but the fighting only has goten worse. I've had my sorority for like 8 months. When looking into sororities i came accross somone that warned me about that. Now i have a five girl sorority and 4 females that have thier own 3/4 to 1 gal bowls. alot more work for me but i did know the chance of that happening. So far as the girl tearing her fins when she is alone. Yep!! I have seen my girls get into some very strange positions! I mean really really strange!! LOL sort of like what was she thinking? thankfully they manage to get themselfs out, (knock on wood) but some day i guess that one might not be so lucky. I don't want to sound negitive, but keep an close watch on them. Female bettas are fun and loveable, but when put togeather they can become lil monsters. lol no i really mean that. p.s. the more SILK plants the better, but if the female(s) agressive theres not a lot you can do but remove her(s) .

Yeah, very true. I knew the risk I was taking when I set up this sorority. Right now all of my females are scattered. (Drina may or may not be a male....not sure how that happened. Delta is recovering from getting into it with someone. Ami is in her own little tank. And Zeta has the whole 10g to herself =) )
